This Metal Gear Solid 5: On the Trail mission guide will show you how to get the elusive S Rank as easily as possible on Mission 19. In order to get an S Rank you need to score 130,000 points. We’ll also list the mandatory and optional objectives for you, but the latter aren’t necessary (and are often detrimental) to getting the S Rank. The biggest factor in earning the 130,000 points is your time bonus, so speed is key. Follow our Metal Gear Solid 5 - On the Trail Mission Guide - Mission 19 Walkthrough - How to get S Rank for all the info you need.

Choose the eastern landing zone, as well as a deployment time of 18:00 hours. You’re also going to want to bring your D-Horse, as there isn’t much use for either D-Dog or Quiet. Since we’re going for a fast time, shaving some seconds (or minutes) off traveling is the major key to success here.
When you are on the ground, hop on your horse and immediately start riding southeast. There is a large dotted line on your map, and you are going to follow that all the way to the outpost at the far edge of the mission area. The most southeast building has a prisoner inside of it, and you can sneak in the back window to gain access. Put him on your shoulder, and then toss him out the window. When you get outside, send him to Mother Base with the Fulton Recovery Device. This guy is a Missile Guidance Specialist that will work for your R&D team, so extracting him matters. If you find that going out of your way to snag him prevents you from getting the S Rank, play the mission a second time and ignore this entire first step.
If you don’t care about the prisoner, start from the east landing zone, riding your D-Horse to the east until you hit the road that follows the mountains. Head north, looking for a side road that kicks off to the right. It’s here that you’ll find the Major.
Our best advice is to call in a Bombardment and use the sleeping gas to knock out the entire crew standing by the car. If anyone makes it out awake, shoot them with your tranquilizer gun. When everyone is sleeping, attach a butt-load of Fulton Recover Devices to them and send them back to Mother Base. You can also extract the vehicles if you want, but remember that every second you are in the mission is a few points you aren’t getting toward that S Rank.
When the Commander is gone, ride back the way you came, exiting the hot zone and completing the mission. If you finish this mission in five minutes, you’ll be just shy of the 130,000 points you need for the S Rank, but modifiers like No Retries, No Kills, No Reflex and No Enemy Combat Alerts should put you over the top. Also, if you extract the Major, you’ll get an extra 5,000 points for that objective. When you add all of this up, this one isn’t that hard.
